I did see smbd processes increase in memory over time, but since I
have never monitored smbd this closely before, I'm not sure if this is
normal or not.  I was doing the following memory test every hour and I
was seeing a general trend up in RSS size.

ps -e -o user,pid,rss,args | sort -b -k3,3n | awk '{print
$1,$2,$3,$4}' | tail -n 20 >> /var/log/memory_usage.log

Here are a couple of smbd pids that were increasing over time, showing
the trend I was seeing.  There were multiple smbd (typically around
18-20) running at the time.

       PID  RSS
root 9402 4176 smbd
root 9402 5364 smbd
root 9402 5752 smbd
root 9402 5752 smbd

root 9787 4124 smbd
root 9787 4556 smbd
root 9787 4560 smbd
root 9787 7448 smbd
root 9787 7460 smbd
